lBe it known that l, CHARLES l. GOODWIN, c citizen ofV the United States, residing et.

Kansas City, in the county of Jackson endy marked thereon, which "forni n. part of thisspeciticntion. Y

. This .invention relates toen improved spring; shackle for motor vehicles end the like.

The primary object of the invention is to provide e. strong, durable enclensily ce cessible spring` shackle which, when' applied, will prevent rattling and squenking which is usually present in conventional types of vehicles.

My invention contemplates v s spring shackle wherein there will be n minimum amount ot' friction where-by better lubricntion can be effected because the devicewill hold the grease or lubricant.

l also employ anti-friction bearings c.dinstable to all motion, whether np or down or (lue to longitudinal thrusts.

llic invention is. soconstructed that the bearings cnn be easily adjustable and any standard Hinke oi roller benring can be incorporated in thc structure.

'llie novel iezuurc'smt the invention will become more clearly apparent by reterencel to the following` description in connection with the accompanying drawings, 1n Whichf- Fig. l is a perspective View of one end et the side bar -of the chassis frame to which e spring is secured in accordance with my invention.

The spring l is shown es being fastened to the end oft the. side bar. 2 oi the chassis frame by a bolt 3, one leef .ct the sprin being bent around the holt' in the forni et loop 4 and fastened thereto by e tcpercd 4pin 5, which passes trnnsverseiy through the loo 4 und through e trensveif-se notch 1n the lt 3.
